Living leaves get bits of themselves chomped by the army of leaf-eating folivores from Orangutans to caterpillars. This is a 'bitten leaf' mantis and a very fat one at that. The fatness might just be a huge meal. It might be eggs and 'uncured' foamy ootheca ('egg suitcase'), or it could be sinister. Extremely long thin parasites called horsehair or Gordian worms are known to inhabit mantis bellies. When the worms are ready they make the mantis extremely thirsty and compel it to seek water and drown itself. The worm emerges from the back end of the mantis directly in the water to breed. Some are even known to survive the host being eaten by a predator
